Bonsoir,
Sur brindille morte d'Acer pseudoplatanus. Pouvez-vous me confirmer Prosthecium platanoidis ?
Ascospores : 23-35 x 7-10 µm, cylindro-elliptiques, triseptées, rétrécies au niveau des cloisons, avec des éperons aigus peu visibles aux extrémités, hyalines, guttulées, lisses.
Asques : cylindriques, octosporés. Je n'ai pas remarqué d'appareil apical clairement congophile.
Merci d'avance !
Andgelo

Re : Prosthecium platanoidis
Bonsoir Andgelo
Prosthecium platanoidis semble être une espèce américaine qui n'est pas congénerique avec celle-ci. Le nom correct de votre champignon semble être Calosporella innesii.

Re : Prosthecium platanoidis
Bonjour.
Oui, Enrique, que je salue, a raison.
Tu pourras lire la description de Calosporella innesii dans Mycological research 112 (2008) cette note :
Notes — Calosporella innesii is characterised by hyaline,
mostly 3-septate ascospores with small apical appendages
and has been transferred to Prosthecium by Wehmeyer (1941)
based on its phragmospores with apical appendages. This
generic classification has subsequently been commonly followed.
Barr (1978) argued that the correct epithet for the taxon
should be Prosthecium platanoidis due to priority, but the type
collection of this species is apparently not congeneric with the
current fungus (see notes above). The name to be applied for
the species is therefore C. innesii.
In the original description, Currey (1858) did not provide any
details about collections. There are numerous authentic collections
of the Currey herbarium in K, one of which is here
selected as lectotype. To ensure nomenclatural stability, a
recent well-developed specimen for which a culture is available
is here selected as epitype. The appendages can be seen well
in water mounts even from old herbarium specimens, but they
quickly disappear in KOH mounts.

Et les appendices seront bien visibles avec un montage dans de l'encre de chine.

Re : Prosthecium platanoidis
Un grand merci à vous. J'ai bien fait de vous soumettre ce champignon ''à priori'' facile à reconnaître.
Je viens de lire l'article en question.
Merci encore !

Re : Prosthecium platanoidis
Salut Andgelo,
Personnellement ça ne me gêne pas de l'appeler comme tu l'as fait.
Un des plus courants sur sycomore.

Re : Prosthecium platanoidis
Oui bien sûr il faut le nommer Calosporella innesii, les collègues ont raison.
